# RE: Use for $call_verb

    The idea would be that a verb call: foo:bar(args) would attempt to call
    #0:call_verb(foo, "bar", {@args}) before making the call by itself.  If the
    verb on #0 did not exist (or was -x), it would proceed with the call
    normally,
    if the the built-in raised an error, that would be passed on to the calling
    program, otherwise, the server would pass back whatever call_verb returned
    to
    the caller.

    If NO type checking were done in advance of call_verb, it would be possible
    to
    do something like this:

    {2,1,4,3}:sort();
    <<<<<

    There's something already like this in the works, though not quite as
    extensive as having a hook on #0 for all verb calls (something I think
    you'll find the majority of us don't like the idea of).  They're called
    "frobs"

    Though actually I wouldn't mind having a hook for doing this on lists or
    strings.
